HS Type Mining Hand Chain Hoist Explosion-Proof Manual Chain Block

The HS series mining hand chain hoist is a safe, reliable, compact, and portable light-duty manual mechanical device that requires no external power. It is suitable for use in environments without power sources or in confined spaces requiring precise positioning, such as equipment installation and maintenance, industrial and mining enterprises, warehouses and docks, logistics handling, and construction operations.
CMAC certified, copper-plated design, explosion-proof.
Compact and aesthetic structure, reliable in use, easy to maintain.
Small size, light weight, easy to carry.
All gears and transmission parts are made of high-quality alloy materials with improved traditional heat treatment processes for superior strength and impact toughness.
Multi-point support structure with high rigidity, uniform and reasonable force distribution, high mechanical efficiency, and minimal deformation under heavy loads.
Optimized braking mechanism with dual brake pawls and improved friction pad materials for a more reasonable and reliable safety factor.
The lifting sprocket adopts precision manufacturing technology, which meshes with the lifting chain under load to reduce impact loads.
Built-in safety latch design for easy loading/unloading. The hook is not easily detached even when deformed under heavy loads, enhancing safety.
High mechanical efficiency, with hand force meeting ergonomic requirements for easy operation.
